Mutation origin

• Strain of Origin: C57BL/6
• Project Collection: B2B/CvDC

Mutation description

• Allele Type: Chemically induced (ENU)
• Mutation: Single point mutation
• Mutation details: This ENU-induced mutation was isolated in a screen at the University of Pittsburgh. The molecular lesion is a T to A substitution at nucleotide +2 after coding nucleotide 7398 (c.7398+2T>A, NM_133365) in intron 44. This changes splice donor site G-GT to G-GA (which is assumed to be inactive). (J:175213) Additional incidental mutations were detected in sequencing for the causative mutation, Dnah5^b2b2395Clo, and may be present in stocks carrying this mutation.

Notes

Summative Diagnosis:
Heterotaxy including Situs inversus totalis
Cardiovascular Phenotype: Dextrocardia and and complex congenital heart defects associated with heterotaxy, including anomalous systemic venous return, atrioventricular septal defect (AVSD), right atrial isomerism (RAI), biventricular hypertrophy, and hypoplastic pulmonary artery. Also observed are mutants with situs inversus totatlis without congenital heart defects
Noncardiovascular Phenotype: Abnormal thoracic and abdominal organ situs anomalies, such as left lung isomerism, dextrogastria/levogastria, and dual inferior vena cava (IVC). A few mutants exhibited malaligned sternal vertebra, immotile airway cilia and craniofacial anomalies including micrognathia, cleft palate, duplex kidneys, and short snout

Fyler Codes
The Fyler code developed by The Boston Children's Heart Foundation in Boston Children's Hospital provides a hierarchical clinical diagnosis of congenital cardiovascular defects and other disorders. These codes are used to delineate pathology in the mutant mouse models that parallel human disease and can be cross referenced to the International Pediatric and Congenital Cardiac Code (IPCCC) (http://www.ipccc.net/).
